Hello folks, I recently purchased a 1977 FJ40, it’s currently being lightly restored with the addition of AC, and a few other items, etc. I purchased the Bose, Soundlink Flex Bluetooth speaker, dimensions are: 3.56" H x 7.93" W x 2.06" D (1.300 lb). Thus will serve as both my Bluetooth hands free microphone and music playback, Pandora, etc. I was thinking the ideal location is at underneath the dashboard just below the heater vents. However I’d need to either create or purchase a bracket to hold it there, but something that would easily allow me to remove the speaker when I park for extended periods, to dissuade potential thieves. Anyone done this? Any ideas? Thanks in advance for your assistance.
